HKS Super SQV4 BOV Kit - Subaru WRX VA
Installing this product creates unique sharp & high frequency SQV sound. The SQV IV unit is designed to be located beside the engine so the appurtenance of the engine bay is improved.
The suction-return parts are included (those are necessary to pass the Japanese Automobile Inspection.).
Any engine failure such as engine stall was not occurred during the in-house testing.
This is a complete bolt on kit for your 2015+ WRX
